Abstract
An electrophotographic conductive member comprising: a conductive layer provided on an outer surface of a support, wherein the conductive layer comprises a plurality of domains dispersed in a matrix, the plurality of domains comprise a crosslinked product of a second rubber and a conductive particle, an outer surface of the electrophotographic conductive member is configured of the matrix and an exposed portion of the domain exposed on the outer surface of the electrophotographic conductive member, an impedance is 1.0×10to 1.0×10Ω of the electrophotographic conductive member, and when specific regions are a first region and a second region, a volume resistivity R1 of a portion being not the conductive particle in the first region and a volume resistivity R2 of a portion being not the conductive particle in the second region satisfy R1>R2.
